MP4 Frame Extractor & ZIP Download

About this tool

Load a local MP4 video, fine-tune the extraction range and sampling method, turn frames into images, and save everything as a ZIP archive. The tool targets MP4 containers with browser-playable codecs such as H.264/AVC + AAC and does not support H.265/HEVC. It checks browser limits so even 8K-class sources are handled safely. All processing happens in your browser (nothing is uploaded).

How to use

  1. Select an MP4 under “Video file” and review playback position and audio in the preview.
  2. Use the seek bar or numeric inputs to define the start and end of the range.
  3. Choose an extraction mode and configure interval/count, output format, scale, and filename pattern.
  4. Check the estimated count and click “Start extraction.” Monitor the progress indicator; cancel mid-process if necessary.
  5. When processing completes, a ZIP download starts automatically. You can also capture a single frame from the preview.

Notes

  • Very high resolutions (e.g., 8K) may exceed browser canvas limits. Lower the scale or prepare a downscaled video.
  • Only MP4 files with hardware-playable codecs such as H.264/AVC + AAC are supported. H.265/HEVC and AV1 are not.
  • If the browser supports requestVideoFrameCallback, the estimated FPS updates during preview for better accuracy.
  • VFR (variable frame rate) videos may yield a few extra or missing frames even when extracting all frames.

Warnings

  • Hardware decoding support varies by browser. Safari prefers H.264, Firefox may struggle with high resolutions, and Chrome/Edge depend on OS support—this tool does not handle H.265/HEVC or AV1.
  • Extraction can use significant memory. For large frame counts, split the range or reduce the scale.
  • Only local files are supported; remote URLs cannot be loaded. The browser may become sluggish while the ZIP is created.
